Specification of Letters Patent.

Patented duly a, rare.

Application filed May 25, 1917. Serial No. H0243.

7 To all whom it may concern:

Be it known that ll, J OHN MioHEL, a citizen of United States, residing at 3018 N. 'Taney street, Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Vulcanizers, of which the following is a specification.

This invention relates to vulcanizers of the type particularly employed for repairing or mending rubber articles.

The primary objects of the invention reside in the provision of an efficient and serviceable vulcanizer of a light and portable nature, inexpensive to manufacture, capable of being easily operated in a correct manner by unskilled persons, not likely to become broken or out of order, and having securing means formed therewith for, securely fastening the same to a suitable stationary support in order to be in a position for active operation.

With these and other objects in view, the invention consists in the novel features of construction, combination of elements and arrangement of parts, hereinafter fully set forth in the following description, and the scope of which is indicated by the appended claims.

In the drawing Figure 1 is a vertical sectional view taken through the preferred form of the vulcanizer comprising the present invention.

Fig. 2 is a transverse sectional view, taken along the line 2 2 of Fig. 1.

Similar characters of reference denote corresponding parts throughout the several views of the drawing.

Referring to the details of the present invention, the letter A designates a vulcanizer constructed in accordance with the inven tion, the same including a bracket or frame 1, formed to provide an enlarged shelf portion 2. The portion 2 is provided with an integral recess arm 8, suitably braced by means of a web 1. The lower portion of the arm 3 extends parallel with the shelf 2, and is provided with a threaded opening for the reception of a hand-manipulated securing screw 5. In securing the bracket to a stationary support or the like 6, the latter is inserted or positioned within the recess de fined between the arm 3 and the shelf 2: then by revolving the screw 5the frame 1 may be When it is desired to secure the frame upon a Wall, not shown, or other similar surface, instead of placing the same upon the shelflike support 6, the frame is provided with laterally extending bifurcated ears 7 ,which are employed to receive suitable securing positioned upon the shelf 2 and has the lower end thereof provided with an opening 11. A fuel holder or cup 12 is adapted to be inserted into the drum by way of the opening 11, so as to be centrally located therein, lugs 13 formed with the shelf 2 being employed to facilitate the positioning of the fuel holder within the drum. The holder 12 is preferably hollow in cross section and is adapted to receive a quantity of fibrous packing 14, which may be saturated with alcohol or the like and is retained within the holder by means of a netting 15.

A. table or plate 16 is mounted upon the upper extremity of the driun 1.0, so as to completely cover the latter, depending lugs 17 formed with the table and being employed to engage with the interior wall of said drum, soas to prevent lateral displacement of the plate 16. Set screws or the like I 18 are threaded into the drum and engage with the lugs 17, whereby the plate will be rigidly secured to said drum. The peripl1- eral edge of the table or plate 16 is provided with depending baiile plates 19, which are located in radial alinement with openings 20 provided in the approximate upper extremity of the drum 10, said opening being utilized to permit gases of combustion, generated by the fuel burner 12, to escape from the drum 10. The plates 19 are em ployed to deflect such escaping gases so that the same will not come in direct contact with a tire 21 or the like carried by the table, as the heated gases emitted by the drum would have a distinctly detrimental effect upon the tire;

In order to provide means for efficiently securing the tire 21 upon the table 16, and to press a repairing patch 22 in close engagement therewith, use is made of a clamping plate 23, which is adapted to be post canizer has been connected with a support,

as shown in Fig. 1, the damaged portion of the tire or article to be repaired is covered withthe soft rubber patch 22, and is placed on the heating table 16. The pressure screw 25 is then operated to force the plate 23 into firm engagement with the tire, so that the latter cannot slip or =1nove over the surface-of the heating table. After this has been accomplished the fuel in the cup or holder 12 is ignited, and'allowcd to burn until all of the same has been con sumed, which will complete the process of vulcanizing the patch 22 with thetir'e 21. Subsequent to this operation the 'parts'are allowed to cool, and the tire may then be removed from engagement with the vulcanizer, and will be in an efficiently repaired condition. 7

Fromthe foregoin description, taken in connection with the accompanyingdrawing, it will be apparent that a vulcanizer for the purpose set forth has been provided which, though comprising few parts, is highly 'eiiieient and practicable for achieving the objects specified.

Having thus describedthe invention what is claimed as new is:

1.,In a vulcanizer, the combination with a frame, a vertically extending heating drum mountedupon the frameand having an opening in the 'wall thereof,a fuel cup adapted to be positioned within the drum through the opening to rest upon-theframe, a heating table closing the upper extremity of the drum, said drum having exhaust openings adjacent the upper end, baffles depending from the peripheral edge of the table to deflect the heat escaping through the openings, a-clan'ipingplate coop'eratii-i'g with said table to impart pressure upon articles positioned upon the table, means for effecting anadju stment of said clamping p1ate,.and means formed on the frame 1 for attaching the latter to either a vertical or horinontal support with the drum vertically' disposed.

Copies of this patent may .be obtained for 2. In a vulcanizer, the combination with a frame having a horizontally disposed ledge, means for securing the frame to a vertical or horizontal support, a heating drum secured to the f nine and having one end resting upon the ledge, said drum having an opening in the front thereof, a

burner adapted to rest upon the ledge and positioned within the drum through said opening, a table closing the upper end of the drum and detachabl-y secured thereto, said drum. having exhaust openings adjacent its upper edge, balile plates depending from said table for deflecting the heat escaping from the drum through said openings, a combined clamping and bracing element, and a frame -arricd screw for controlling the action of said element for the purpose specified.

3. In a vulcanizer, the combination with aframe including a horizontal ledge, a heat ing drum reposing vupon said ledge and vertically disposed, said drum having an enlarged opening, a burner adapted to bepositioned within the drum through said opening to rest upon said lodge,lugs rising from the ledge and coacting with the burner to maintain the latter in proper position within the drum, a table closing the upper end of the drum, said drum having exhaust. openings adjacent its upper end, ballie plates depending from said table for-deflecting heat'escaping from the drum throughsaid openins, yoke shaped arm formed on the frame, a tire-clamping and bracing plate, and an adjusting screw threadedly asso- 'ciated with the yoke for controlling the action of said plate.

4. In a vulcanizor, the combination with a frame having a horizontally disposed lodge, a heating drum supported endwisc upon said ledge, a burner supported upon said ledge within the drum and spaced from the walls of the latter, said drum having heat-exhaust openings adjacent its upper end, a table closing the upper end ofthe drum, lugs depending from thetable and engaged against the inner wall of the drum, fastening elements carried by the drum, and engagingsaid lugs for rcmovablyholding the table in proper position upon the latter, batli'es dependingfrom said table for deflecting the heat escaping from the drum through said openings, a combined cl-an'ip ing and bracing plate arr: nged above the table, and means for adjusting said plate to impart prcssure'npon articles positioned upon the'ta'ble;

In testimony whereof I affix-my signatu re.
